　保持空間５０の長辺は、０．３ｍｍ未満の場合、舌から除去された汚れの保持性に対して好ましくない影響を及ぼす可能性を有する。保持空間５０の長辺は、１０．０ｍｍよりも大きい場合、清掃突起４３の形成のためのスペースが減少する等の好ましくない影響を及ぼす可能性を有する。 When the long side of the holding space 50 is less than 0.3 mm, it may have an unfavorable influence on the holding property of the dirt removed from the tongue. When the long side of the holding space 50 is larger than 10.0 mm, there is a possibility that the space for forming the cleaning protrusion 43 may be adversely affected.
　保持空間５０の深さは、舌から除去された汚れを保持することに適した大きさを有する。保持空間５０の深さは、基礎面４１Ａから保持空間底面３６Ｂまでの距離により規定される。保持空間５０の深さは、清掃突起４３の高さおよび直径の少なくとも一方よりも大きいことが好ましい。保持空間５０の深さは、適正深さ範囲に含まれることが好ましい。適正深さ範囲は、一例として、０．３ｍｍ～２．０ｍｍの範囲を有する。適正深さ範囲は、より好ましい例として、０．５ｍｍ～１．５ｍｍの範囲を有する。保持空間５０の深さは、一例として、０．８ｍｍを有する。 The depth of the holding space 50 has a size suitable for holding dirt removed from the tongue. The depth of the holding space 50 is defined by the distance from the base surface 41A to the holding space bottom surface 36B. The depth of the holding space 50 is preferably larger than at least one of the height and diameter of the cleaning protrusion 43. The depth of the holding space 50 is preferably included in an appropriate depth range. The appropriate depth range has a range of 0.3 mm to 2.0 mm as an example. The appropriate depth range has a range of 0.5 mm to 1.5 mm as a more preferable example. The depth of the holding space 50 has 0.8 mm as an example.
　保持空間５０の深さは、０．３ｍｍ未満の場合、舌から除去された汚れの保持性に対して好ましくない影響を及ぼす可能性を有する。保持空間５０の深さは、２．０ｍｍよりも大きい場合、保持空間５０の清掃時における汚れの放出性に対して好ましくない影響を及ぼす可能性を有する。 When the depth of the holding space 50 is less than 0.3 mm, there is a possibility that the holding space 50 may have an unfavorable influence on the holding property of the dirt removed from the tongue. If the depth of the holding space 50 is larger than 2.0 mm, there is a possibility that the holding space 50 may have an unfavorable influence on the soil release property when the holding space 50 is cleaned.
　汚れの保持性は、除去された汚れを保持することに関する保持空間５０の能力を示す。汚れの保持性に対する好ましくない影響は、保持空間５０において十分な量の汚れが保持されにくくなることを含む。十分な量は、使用者が保持空間５０に保持されている汚れを容易に視認することができる量を示す。 Dirty retention indicates the ability of the holding space 50 to hold the removed dirt. Undesirable influences on dirt retention include that it becomes difficult to hold a sufficient amount of dirt in the holding space 50. The sufficient amount indicates an amount by which the user can easily visually recognize the dirt held in the holding space 50.
　図１および図５を参照して、電動口腔衛生装置１の作用について説明する。 The operation of the electric oral hygiene device 1 will be described with reference to FIG. 1 and FIG.
　舌清掃器具１０は、歯の清掃に用いられる場合、歯清掃部１１が歯に押し当てられる。舌清掃器具１０は、衛生装置本体６０により駆動されることにより、器具長手方向に沿って歯に対して往復移動する。または、舌清掃器具１０は、使用者により操作されることにより、歯に対して往復移動する。舌清掃器具１０は、歯に対して移動することにより、歯清掃部１１により歯の汚れを除去する。 When the tongue cleaning device 10 is used for cleaning teeth, the tooth cleaning unit 11 is pressed against the teeth. The tongue cleaning device 10 is driven by the sanitary device body 60 to reciprocate with respect to the teeth along the longitudinal direction of the device. Or the tongue cleaning instrument 10 reciprocates with respect to a tooth | gear by being operated by the user. The tongue cleaning device 10 moves with respect to the teeth, thereby removing the dirt on the teeth by the tooth cleaning unit 11.
　舌清掃器具１０は、舌の清掃に用いられる場合、舌清掃部４０が舌に押し当てられる。舌清掃器具１０は、弱い力により舌に押し当てられることが好ましい。舌清掃器具１０は、衛生装置本体６０により駆動されることにより、器具長手方向に沿って舌に対して往復移動する。または、舌清掃器具１０は、使用者により操作されることにより、器具長手方向において舌に対して往復移動する。舌清掃器具１０は、舌に対して移動することにより、複数の清掃突起４３により舌の汚れを除去する。 When the tongue cleaning device 10 is used for cleaning the tongue, the tongue cleaning unit 40 is pressed against the tongue. The tongue cleaning device 10 is preferably pressed against the tongue with a weak force. The tongue cleaning instrument 10 is driven by the sanitary device body 60 to reciprocate with respect to the tongue along the instrument longitudinal direction. Or the tongue cleaning instrument 10 reciprocates with respect to a tongue in an instrument longitudinal direction by being operated by the user. The tongue cleaning device 10 moves with respect to the tongue to remove the dirt on the tongue by the plurality of cleaning protrusions 43.
　舌から除去された汚れ（以下、「除去後汚れＳＡ」）は、舌清掃器具１０の往復移動により舌清掃部４０上を移動する。除去後汚れＳＡの一部または全部は、保持空間５０に入り込む。保持空間５０に入り込んだ汚れ（以下、「空間内汚れＳＢ」）は、舌清掃器具１０が舌の清掃に用いられているとき、保持空間５０の外部に移動しにくい。空間内汚れＳＢが保持空間５０の外部に移動しにくいことは、本願発明者が実施した実験の結果により確認されている。その理由は、次のように考えられる。空間内汚れＳＢは、清掃突起４３上に存在する除去後汚れＳＡと比較して、舌清掃器具１０が往復移動するときに舌に接触しにくい。このため、舌との接触による空間内汚れＳＢの移動が生じにくい。このため、空間内汚れＳＢは、保持空間５０の外部に移動しにくい。 The dirt removed from the tongue (hereinafter, “soil after removal SA”) moves on the tongue cleaning unit 40 by the reciprocating movement of the tongue cleaning device 10. Part or all of the post-removal dirt SA enters the holding space 50. Dirt that has entered the holding space 50 (hereinafter, “in-space dirt SB”) is difficult to move to the outside of the holding space 50 when the tongue cleaning device 10 is used for cleaning the tongue. It is confirmed by the results of experiments conducted by the inventors of the present application that the in-space dirt SB is difficult to move to the outside of the holding space 50. The reason is considered as follows. The in-space dirt SB is less likely to come into contact with the tongue when the tongue cleaning instrument 10 reciprocates as compared to the after-removal dirt SA present on the cleaning protrusion 43. For this reason, the movement of the dirt SB in the space due to contact with the tongue hardly occurs. For this reason, the in-space dirt SB is unlikely to move outside the holding space 50.
　空間内汚れＳＢは、舌清掃器具１０が口腔内から取り出された後、舌清掃器具１０が水等の洗浄液により洗浄されることにより、保持空間５０の外部に移動する。保持空間５０の外部に移動した汚れ（以下、「洗浄後汚れＳＣ」）は、舌清掃器具１０から除去される。このため、舌清掃器具１０の衛生的な状態が形成される。 The in-space dirt SB moves to the outside of the holding space 50 when the tongue cleaning device 10 is washed with a cleaning liquid such as water after the tongue cleaning device 10 is taken out from the oral cavity. Dirt that has moved to the outside of the holding space 50 (hereinafter, “post-cleaning dirt SC”) is removed from the tongue cleaning device 10. For this reason, the sanitary state of the tongue cleaning instrument 10 is formed.
　図６を参照して、舌から除去された汚れの程度の確認手順について説明する。 Referring to FIG. 6, the procedure for confirming the degree of dirt removed from the tongue will be described.
　使用者は、舌清掃器具１０により舌を清掃する。使用者は、舌清掃器具１０を口腔内から取り出す。使用者は、保持空間５０に存在する空間内汚れＳＢの量を視認する。使用者は、空間内汚れＳＢが存在していることを確認した場合、舌の汚れが除去されたことを認識することができる。使用者は、空間内汚れＳＢが存在していることを確認した場合、舌に汚れが残されている可能性があることを認識することができる。使用者は、舌清掃器具１０により舌を引き続き清掃する場合、洗浄液により保持空間５０を洗浄する。空間内汚れＳＢは、洗浄後汚れＳＣとして保持空間５０から洗い流される。 The user cleans the tongue with the tongue cleaning device 10. The user takes out the tongue cleaning device 10 from the oral cavity. The user visually recognizes the amount of in-space dirt SB present in the holding space 50. When the user confirms that the in-space dirt SB exists, the user can recognize that the dirt on the tongue has been removed. When the user confirms that the in-space dirt SB exists, the user can recognize that there is a possibility that dirt is left on the tongue. When the user continues to clean the tongue with the tongue cleaning device 10, the user cleans the holding space 50 with the cleaning liquid. The in-space dirt SB is washed away from the holding space 50 as the after-cleaning dirt SC.
　使用者は、舌清掃器具１０により舌を再び清掃した後、上記と同様の手順により、空間内汚れＳＢが存在するかどうかを確認する。使用者は、舌清掃器具１０を口腔内から取り出した後において、空間内汚れＳＢが確認できなくなるまで、舌の清掃を継続することができる。使用者は、舌清掃器具１０を口腔内から取り出した後において、空間内汚れＳＢが確認できないとき、舌の汚れが十分に除去されたことを認識することができる。 After the user cleans the tongue again with the tongue cleaning device 10, the user confirms whether there is dirt SB in the space by the same procedure as described above. After the user removes the tongue cleaning device 10 from the oral cavity, the user can continue cleaning the tongue until the in-space dirt SB cannot be confirmed. The user can recognize that the dirt on the tongue has been sufficiently removed when the in-space dirt SB cannot be confirmed after the tongue cleaning device 10 is taken out from the oral cavity.
　図６を参照して、舌清掃器具１０の製造方法について説明する。 With reference to FIG. 6, the manufacturing method of the tongue cleaning instrument 10 is demonstrated.
　舌清掃器具１０の製造方法（以下、「器具製造方法」）は、一例として、射出成形法を含む。器具製造方法は、１次成形工程および２次成形工程を含む。器具製造方法は、基礎成形型１００、１次成形型１１０、および２次成形型１２０を用いて舌清掃器具１０を製造する。 The method for manufacturing the tongue cleaning device 10 (hereinafter referred to as “device manufacturing method”) includes, as an example, an injection molding method. The instrument manufacturing method includes a primary molding process and a secondary molding process. In the instrument manufacturing method, the tongue cleaning instrument 10 is manufactured using the basic mold 100, the primary mold 110, and the secondary mold 120.
　基礎成形型１００は、一例として、図６（ａ）に示される構造を有する。基礎成形型１００は、器具本体２０を成形するための構造を有する。１次成形型１１０は、一例として、図６（ａ）に示される構造を有する。１次成形型１１０は、器具本体２０を成形するための構造を有する。２次成形型１２０は、一例として、図６（ｂ）に示される構造を有する。２次成形型１２０は、器具本体２０に舌清掃部４０を成形するための構造を有する。２次成形型１２０は、２次成形部１２１、成形品固定部１２２、およびゲート１２３を有する。２次成形型１２０は、基礎成形型１００と２次成形部１２１との間に２次成形空間１２４を形成する。 The basic mold 100 has a structure shown in FIG. 6A as an example. The basic mold 100 has a structure for molding the instrument body 20. As an example, the primary mold 110 has a structure shown in FIG. The primary mold 110 has a structure for molding the instrument body 20. As an example, the secondary mold 120 has a structure shown in FIG. The secondary mold 120 has a structure for forming the tongue cleaning unit 40 in the instrument body 20. The secondary mold 120 includes a secondary molding part 121, a molded product fixing part 122, and a gate 123. The secondary mold 120 forms a secondary molding space 124 between the basic mold 100 and the secondary molding part 121.
　図６（ａ）は、１次成形工程の作業過程を示している。 FIG. 6A shows the work process of the primary molding process.
　１次成形工程は、最初の段階において、基礎成形型１００に対して１次成形型１１０を型締めする。１次成形型１１０は、型締めされることにより、基礎成形型１００との間に１次成形空間（図示略）を形成する。１次成形工程は、次の段階において、１次成形空間に第１成形材料を射出する。１次成形工程は、第１成形材料を射出することにより、１次成形品としての器具本体２０を成形する。１次成形工程は、次の段階において、１次成形型１１０を型開きする。 In the primary molding step, the primary mold 110 is clamped to the basic mold 100 in the first stage. The primary mold 110 is clamped to form a primary molding space (not shown) between the primary mold 110 and the basic mold 100. In the primary molding step, the first molding material is injected into the primary molding space in the next stage. In the primary molding step, the tool body 20 as a primary molded product is molded by injecting the first molding material. In the primary molding step, the primary molding die 110 is opened in the next stage.
　図６（ｂ）および（ｃ）は、２次成形工程の作業過程を示している。 FIGS. 6B and 6C show the work process of the secondary forming process.
　２次成形工程は、最初の段階において、基礎成形型１００に対して２次成形型１２０を型締めする。２次成形型１２０は、型締めされることにより、基礎成形型１００との間に２次成形空間１２４を形成する。２次成形型１２０は、型締めされることにより、基礎成形型１００との間に２次成形空間１２４を形成する。成形品固定部１２２は、ヘッド３０の基礎部形成面３６に接触する。２次成形型１２０は、成形品固定部１２２によりヘッド３０を基礎成形型１００に押し付ける。 In the secondary molding process, the secondary mold 120 is clamped to the basic mold 100 in the first stage. The secondary mold 120 is clamped to form a secondary molding space 124 between the secondary mold 120 and the basic mold 100. The secondary mold 120 is clamped to form a secondary molding space 124 between the secondary mold 120 and the basic mold 100. The molded product fixing part 122 contacts the base part forming surface 36 of the head 30. The secondary mold 120 presses the head 30 against the basic mold 100 by the molded product fixing part 122.
　２次成形工程は、次の段階において、ゲート１２３を介して２次成形空間１２４に第２成形材料を射出する。２次成形工程は、第２成形材料を射出することにより２次成形品として機能する舌清掃部４０をヘッド３０上に成形する。２次成形工程は、次の段階において、２次成形型１２０を型開きする。 The secondary molding step injects the second molding material into the secondary molding space 124 through the gate 123 in the next stage. In the secondary molding step, the tongue cleaning unit 40 that functions as a secondary molded product is molded on the head 30 by injecting the second molding material. In the secondary molding step, the secondary molding die 120 is opened in the next stage.
　器具製造方法の作用について説明する。 The operation of the appliance manufacturing method will be described.
　基礎成形型１００上の第２成形材料は、基礎成形型１００周囲の第２成形材料から圧力を受ける。言い換えると、第２成形材料は、基礎成形型１００への圧力を受ける。基礎成形型１００周囲の第２成形材料は、基礎成形型１００上の第２成形材料を基礎成形型１００とブラシ植毛面３５との間に移動させる力を、基礎成形型１００上の第２成形材料に付与する。このため、ヘッド３０は、基礎成形型１００から離れる方向の力を第２成形材料から受けている。このため、成形品固定部１２２が存在していないと仮定した場合、２次成形工程においてヘッド３０が基礎成形型１００から離れるおそれがある。すなわち、第２成形材料が基礎成形型１００とブラシ植毛面３５との間に流れ込むおそれがある。このため、完成後の成形品のブラシ植毛面３５に第２成形材料が溶着することがある。 The second molding material on the basic mold 100 receives pressure from the second molding material around the basic mold 100. In other words, the second molding material receives pressure on the basic mold 100. The second molding material around the basic mold 100 is the second molding material on the basic mold 100 by applying a force to move the second molding material on the basic mold 100 between the basic mold 100 and the brush flocking surface 35. Giving to the material. For this reason, the head 30 receives a force in a direction away from the basic mold 100 from the second molding material. For this reason, when it is assumed that the molded product fixing portion 122 does not exist, the head 30 may be separated from the basic mold 100 in the secondary molding process. That is, the second molding material may flow between the basic mold 100 and the brush flocking surface 35. For this reason, a 2nd molding material may weld to the brush flock surface 35 of the molded product after completion.
　本器具製造方法は、２次成形工程において、成形品固定部１２２によりヘッド３０を基礎成形型１００に押さえ付けている。このため、第２成形材料から受ける圧力によりヘッド３０が基礎成形型１００から離れることが抑制される。すなわち、基礎成形型１００とブラシ植毛面３５との間に第２成形材料が流れ込むことが抑制される。このため、完成後の成形品のブラシ植毛面３５に第２成形材料が溶着することが抑制される。 In this instrument manufacturing method, the head 30 is pressed against the basic mold 100 by the molded product fixing portion 122 in the secondary molding process. For this reason, it is suppressed that the head 30 leaves | separates from the basic mold 100 with the pressure received from a 2nd molding material. That is, the second molding material is suppressed from flowing between the basic mold 100 and the brush flocking surface 35. For this reason, it is suppressed that a 2nd molding material welds to the brush flock surface 35 of the molded article after completion.
　電動口腔衛生装置１は、以下の効果を奏する。 The electric oral hygiene device 1 has the following effects.
　（１）電動口腔衛生装置１は、舌清掃器具１０を有する。舌清掃器具１０は、舌清掃部４０を有する。舌清掃部４０は、清掃部基礎部４１、複数の清掃突起４３、および保持空間５０を有する。保持空間５０は、清掃部基礎部４１に対して凹んだ形状を有する。この構成によれば、舌から除去された汚れが保持空間５０において保持される。このため、使用者は、舌清掃器具１０により舌を清掃した後、保持空間５０の汚れを確認することにより、舌から除去された汚れの程度を認識することができる。このように、電動口腔衛生装置１は、舌から除去された汚れの程度を使用者に認識させることに貢献する。 (1) The electric oral hygiene device 1 has a tongue cleaning device 10. The tongue cleaning device 10 has a tongue cleaning unit 40. The tongue cleaning unit 40 includes a cleaning unit base 41, a plurality of cleaning protrusions 43, and a holding space 50. The holding space 50 has a recessed shape with respect to the cleaning unit base portion 41. According to this configuration, the dirt removed from the tongue is held in the holding space 50. For this reason, the user can recognize the degree of dirt removed from the tongue by checking the dirt in the holding space 50 after cleaning the tongue with the tongue cleaning device 10. Thus, the electric oral hygiene device 1 contributes to making the user recognize the degree of dirt removed from the tongue.
　（２）使用者は、舌清掃器具１０を口腔内から取り出した後において、保持空間５０に汚れが存在していないことを確認したとき、舌の汚れが十分に除去されたことを認識することができる。このため、舌清掃器具１０により舌が過剰に清掃されることが抑制される。なお、舌の過剰な清掃は、舌清掃器具１０を用いて舌が長期間にわたり清掃されること、または舌清掃器具１０を用いて舌が強い力により清掃されることを示す。 (2) When the user confirms that the dirt is not present in the holding space 50 after removing the tongue cleaning device 10 from the oral cavity, the user recognizes that the dirt on the tongue has been sufficiently removed. Can do. For this reason, excessive cleaning of the tongue by the tongue cleaning device 10 is suppressed. It should be noted that excessive cleaning of the tongue indicates that the tongue is cleaned over a long period of time using the tongue cleaning device 10 or that the tongue is cleaned with a strong force using the tongue cleaning device 10.
　（３）保持空間底面３６Ｂは、外部に露出している。保持空間底面３６Ｂは、ヘッド形成色ＣＨＡを有する。舌清掃部４０は、清掃部形成色ＣＣＡを有する。ヘッド形成色ＣＨＡおよび清掃部形成色ＣＣＡは、互いに相違する。このため、保持空間底面３６Ｂと基礎面４１Ａとの色の相違が形成される。この構成によれば、使用者は、保持空間底面３６Ｂを容易に視認することができる。このため、使用者は、保持空間５０の位置を容易に視認することができる。このため、使用者は、舌から除去された汚れの程度を速やかに確認することができる。 (3) The holding space bottom surface 36B is exposed to the outside. The holding space bottom surface 36B has a head forming color CHA. The tongue cleaning unit 40 has a cleaning unit forming color CCA. The head formation color CHA and the cleaning part formation color CCA are different from each other. For this reason, a color difference is formed between the holding space bottom surface 36B and the base surface 41A. According to this configuration, the user can easily visually recognize the holding space bottom surface 36B. For this reason, the user can easily visually recognize the position of the holding space 50. For this reason, the user can quickly confirm the degree of dirt removed from the tongue.
　（４）舌清掃器具１０では、ヘッド形成色ＣＨＡを利用して、保持空間底面３６Ｂの色が、基礎面４１Ａとの色と相違している。この構成によれば、ヘッド形成色ＣＨＡを利用することなく、保持空間底面３６Ｂの色が基礎面４１Ａの色と相違する構成と比較して、舌清掃器具１０の製造時の工程が少なくなる。このため、舌清掃器具１０は、製造コストの低減に貢献する。 (4) In the tongue cleaning instrument 10, the color of the holding space bottom surface 36B is different from the color of the base surface 41A using the head forming color CHA. According to this structure, the process at the time of manufacture of the tongue cleaning instrument 10 decreases compared with the structure from which the color of holding | maintenance space bottom face 36B differs from the color of 41 A of base surfaces, without utilizing head formation color CHA. For this reason, the tongue cleaning instrument 10 contributes to the reduction of manufacturing cost.
　（５）保持空間５０は、清掃部基礎部４１のうちのヘッド先端側部３２上に存在する部分に形成されている。この構成によれば、清掃部基礎部４１のうちのヘッド基端側部３１上に存在する部分に保持空間５０が形成されていると仮定した構成と比較して、舌から除去された汚れが保持空間５０に入り込みやすい。このことは、本願発明者が実施した実験の結果により確認されている。この結果が得られた理由は、舌の清掃時において舌清掃器具１０が器具長手方向に沿って往復移動することが関係していると考えられる。 (5) The holding space 50 is formed in a portion of the cleaning unit base portion 41 that exists on the head tip side portion 32. According to this configuration, dirt removed from the tongue is compared with the configuration in which the holding space 50 is assumed to be formed in a portion of the cleaning unit base portion 41 on the head base end side portion 31. It is easy to enter the holding space 50. This has been confirmed by the results of experiments conducted by the present inventors. The reason why this result was obtained is considered to be related to the fact that the tongue cleaning device 10 reciprocates along the longitudinal direction of the device when cleaning the tongue.
　（６）舌清掃部４０は、適正高さ範囲に含まれる清掃突起４３の高さを有する。この構成によれば、清掃突起４３の高さが、舌の清掃性に対して好ましくない影響を及ぼすことが抑制される。 (6) The tongue cleaning unit 40 has the height of the cleaning protrusion 43 included in the appropriate height range. According to this structure, it is suppressed that the height of the cleaning protrusion 43 exerts an undesirable influence on the cleaning performance of the tongue.
　（７）舌清掃部４０は、適正直径範囲に含まれる清掃突起４３の直径を有する。この構成によれば、清掃突起４３の直径が、舌の清掃性に対して好ましくない影響を及ぼすことが抑制される。 (7) The tongue cleaning unit 40 has the diameter of the cleaning protrusion 43 included in the appropriate diameter range. According to this structure, it is suppressed that the diameter of the cleaning protrusion 43 exerts an undesirable influence on the cleaning performance of the tongue.
　（８）舌清掃部４０は、適正短辺範囲に含まれる保持空間５０の短辺を有する。この構成によれば、保持空間５０の短辺が、舌から除去された汚れの保持性に対して好ましくない影響を及ぼすことが抑制される。また、保持空間５０の短辺が、清掃突起４３の形成のためのスペースに対して好ましくない影響を及ぼすことが抑制される。 (8) The tongue cleaning unit 40 has the short side of the holding space 50 included in the appropriate short side range. According to this configuration, it is possible to suppress the short side of the holding space 50 from adversely affecting the holding performance of the dirt removed from the tongue. Further, it is possible to suppress the short side of the holding space 50 from adversely affecting the space for forming the cleaning protrusion 43.
　（９）舌清掃部４０は、適正長辺範囲に含まれる保持空間５０の長辺を有する。この構成によれば、保持空間５０長辺が、舌から除去された汚れの保持性に対して好ましくない影響を及ぼすことが抑制される。また、保持空間５０の長辺が、清掃突起４３の形成のためのスペースに対して好ましくない影響を及ぼすことが抑制される。 (9) The tongue cleaning unit 40 has the long side of the holding space 50 included in the appropriate long side range. According to this configuration, the long side of the holding space 50 is suppressed from adversely affecting the holding performance of the dirt removed from the tongue. Further, it is possible to suppress the long side of the holding space 50 from adversely affecting the space for forming the cleaning protrusion 43.
　（１０）舌清掃部４０は、適正深さ範囲に含まれる保持空間５０の深さを有する。この構成によれば、保持空間５０の深さが、舌から除去された汚れの保持性に対して好ましくない影響を及ぼすことが抑制される。また、保持空間５０の深さが、保持空間５０の清掃時における汚れの放出性に対して好ましくない影響を及ぼすことが抑制される。 (10) The tongue cleaning unit 40 has a depth of the holding space 50 included in an appropriate depth range. According to this structure, it is suppressed that the depth of the holding | maintenance space 50 has an unfavorable influence with respect to the retainability of the dirt removed from the tongue. Further, it is possible to suppress the depth of the holding space 50 from undesirably affecting the dirt release property when the holding space 50 is cleaned.
　（１１）器具製造方法は、２次成形工程において、成形品固定部１２２によりヘッド３０を基礎成形型１００に押さえ付ける。この構成によれば、２次成形工程後の成形品のブラシ植毛面３５に第２成形材料が溶着することが抑制される。また、２次成形工程後の成形品の清掃部周壁部４２にバリが形成されにくい。 (11) In the instrument manufacturing method, the head 30 is pressed against the basic mold 100 by the molded product fixing portion 122 in the secondary molding process. According to this structure, it is suppressed that a 2nd molding material welds to the brush flock surface 35 of the molded article after a secondary shaping | molding process. Moreover, it is difficult to form burrs on the cleaning portion peripheral wall portion 42 of the molded product after the secondary molding step.
　（第２実施形態）
　第２実施形態の電動口腔衛生装置１は、次の点において第１実施形態の電動口腔衛生装置１と相違し、その他の点において第１実施形態の電動口腔衛生装置１と同じ構成を有する。第１実施形態の電動口腔衛生装置１の舌清掃器具１０は、図４に示される構造を有する。第２実施形態の電動口腔衛生装置１の舌清掃器具１０は、図７に示される構造を有する。なお、第２実施形態の電動口腔衛生装置１において、第１実施形態の電動口腔衛生装置１と共通する構成については同一の符号を付して、その説明の一部または全部を省略する。 (Second Embodiment)
